Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.


Safety Data Sheet

Description
This kit has been designed to allow the analyst to perform a very simple colorimetric analysis to determine the ammonia nitrogen concentration of their freshwater sample. The analysis yields an easily identifiable color transition that can be compared with the included color key to determine the concentration in your sample. The kit contains everything an analyst would need to perform a water analysis either in the laboratory setting or out in the field. Kit contains enough materials to perform 40 tests.

Concentration Reader Range:
0, 0.25, 0.5, 0.75, 1.0, 1.5 and 2.0 mg NH
Higher concentrations can be tested using a dilution of the water sample with DI water (not supplied)

Aligned to the Next Generation Science Standards (NGSS)*
